ferent shape or construction from the inter-` y `mediate struts, which renders the construction as well as assembly an expensive process.`

It is therefore a general object of the invention to simplify and improve the construction of cloth boards of this character.

It is a specific object of the invention to prevent twisting or lateral displacement of the strut member, so as to improve the rigidity of the board.

Other objects and features of novelty Will be apparent from the following description and the accompanying drawings, in which Fig. 1 is a plan view partly in section of my improved cloth board;

Fig. 2 is an end elevation of the structure shown in Fig. 1; and

F ig. 3 is a cross-section taken along the line 3 3 of Fig. 1.

Referring more particularly to the drawings, the embodiment of my invention shown therein comprises a pair of hollow side members 10, and a plurality of strut members 11 arranged perpendicularly thereto. The member may be formed of a pasteboard tube. A series of rectangular slots 12 are formed by cutting substantially half Way through the tube at spaced intervals. The ends are similarly cut away forming notches 13, having their outer sides open.

The strut members 11 may be formed of any light material, preferably wood. `Each side of each end of thestrut 11 is notched as at 14, formino' a shoulder of a depth to the thidliness of the wall 15 of the tube 10. The central portion of the end of the strut is shaped to fit thel hollow interior of the tube l0, and in the embodiment of the invention shown comprises a vsemicircular portion 16. n When the side members 10 and the struts l0 1s preferably cylindrical, andA l1 have been constructed as described above, they may be assembled by merely fitting the ends of thestruts in the notches or slots of the side member 10, and secured in place by gluing or other suitable fastening means.

It should be noted that members 11 is identical. This permits very rapid assembly, as the mechanic is not required to Vselect a different strut member for the end notches and the intermediate slots. Furthermore, the slot 12 and the notch 13 each of the strut y may be constructed with the same tool, the

only difference being that the cut end of the tube removes the outer side of the-notch 13;

Another advantage lies inthe fact that the strut 11 passes through the notch 12 and the end portion 16` fits snugly against the hollow interior of the tube and at the same time the edge of the slot 12 fits into the notch 14 and abuts the shoulder formed thereby. A very rigid construction is therefore accomplished, not only by the snug fits provided but also by the curved edge of the slot 12 abutting against the flat side of the strut 11.

This construction not only prevents lateral movement of the struts, but also prevents their pivoting about their end attach-4 ments. An added feature resides in the fact that the notch 14 permits the edge of the strut 11 to be flush with the outer surface of the tube 10 so that there is no projecting end, and a smooth exterior surface is provided. While the invention has been shown and described in greatdetail for one embodiment of the broad idea, it is not limited to the details shown but includes such modifications y as come Within the scope of the appended claim.

'form `the end members and intermediate members of said frame, each of said tubes being cut substantially half way through their adjacent sides at the ends and at spaced intervalsby aligned rectangular slots to receive t-he ends of said struts, the ends of `sides of said slots and prevent lateral dis- 10 placement of the struts, each of said struts being identical, whereby any strut may be placed in any aligned pair of slots during assembly.

In testimony whereof I hereunto affix my 16 signature.

CLARENCE HARRY FORNEY.
